BTU Ratings for every NRA gun safe shown on safe door!
We've made calculating BTUs easy for you
- Every Series of NRA gun safes show their ratings based on steel thickness and layers of fireboard.
- The BTU chart assumes there are no weak links (meaning all safes use balanced 5/8" layers, the best heat expanding fire seal and effective door bolt coverage).
- You will also notice that we included the equivalent TIME and TEMPERATURE ratings. When a competitor's safe says 60 minutes, you will now be able to see how much insulation is required to achieve that rating. Anything less is just smoke and mirrors. Pretty cool, huh?
